Celtic boss Gordon Strachan was about to deploy Roy Keane in a defensive role - until Dundee United scored while the player was in the toilet.
"We had one plan at 3-1 and another plan at 3-2," Strachan said after his side were held 3-3 at Celtic Park.
"It was going to be a shutting up job, but we didn't have the time to get him on and I had to keep all my attackers.
"It's happened before. It's not Roy's fault. I felt a bit sorry for him, but he has taken it well."
